arXiv:2606.05878v1 Announce Type: new Abstract: Foundation models mark a profound paradigm shift in time series modeling, with task-specific models being superseded by general-purpose zero-shot models. Yet, current approaches primarily focus on forecasting, while real-world time series are often irregularly and partially observed, requiring models that can jointly forecast, impute missing values, and handle degraded sampling conditions. To address these challenges, we introduce TS-ICL, a novel probabilistic In-Context Learning encoder--regressor Transformer that unifies forecasting and imputat
The proliferation of time series data and the maturity of foundation models are converging, pushing the boundaries of general-purpose AI for complex temporal data.
This development indicates a move towards more robust and versatile AI models capable of handling real-world, messy time series data across various applications.
Time series analysis shifts from task-specific models towards unified, general-purpose foundation models that can perform multiple functions like forecasting and imputation.
